HAY-PRESS.

SPECIFICATION forming part of Letters Patent .N o. 670,421, dated March26, 1901. Application filed September 11, 1900. Serial No. 29,671. (Nomodel.)

To all?, whom t may concern:

Be it known that I, ROBERT D. EMMoNs, a citizen of the United States,residing at Meridian, in the county of Lauderdale and State ofMississippi, have invented a new and useful Hay-Press, of whichthefollowing is a specification.

This invention relates to presses in general, and more particularly tothat class employed in baling hay, straw, &c., the object of theinvention being to provide a construction in which a maximum compressionwill be secured with a minimum of energy applied and in which,furthermore, the plunger will be released and returned after eachoperation and in which the ends of the straws will be tucked into thepress to form a neat bale.

Additional advantages and objects of the invention will be evident fromthe following description. v

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a perspective view showing the complete baling-press in itsoperative position. Fig. 2 isa central longitudinal section of thepress. Fig. 3 is a plan View showing the toggle-levers and theiroperating means.

Referring now to the drawings, the press comprises a boX,including abase 5 and sides 6 and 7, the rear portions of the sides being slotted,as shown, and which is the usual construction, this slotted portionhaving a top 8. Cross-braces 9 are secured to the under side of the box,and additional braces 10 are disposed transversely of the upper sidethereof, these braces being perforated for the reception of the usualtie-rods 11, there being employed also the usual vertical braces 12,having tie-rods 13 at their ends.

Between the foremost cross-brace 9 and the one in the rear thereof isthe hopper, through which the material to be baled is contributed to thepress, the front edge of the hopper being formed by the rear edge of atop portion 14 for the front end. of the press-box.

A plunger or piston 15 is disposed within the press-box and is providedwith a rod 16,

which is operated in a manner hereinafter described to perform thepressing operation.

To provide for tu cking the ends of the straw or hay into the press,atucker is arranged at the rear side of the hopper, this tuckerconsisting of a board or plate 16', fixed upon a shaft 17, which isrotatably mounted in the sides of the press-box in such a manner thatwhen the tucker is in a vertical plane its side kabove the shaft 17 willlie against the front lit pivotally, causing the upper edge thereof tomove downwardly and tuck the ends of the straws and hay into thepress-box, the upper end of the plunger being cut away at its forwardportion to receive the tucker and to permit sufficient space under it toallow thetucked ends to be drawn from under the plate as the plunger isreturned. When the plunger is withdrawn, the tucker returns to itsformer position.

The plunger-operating mechanism is'mounted at the outer end of a sill20, which may be attached to or formed integral with the base of thepress-box, and it consists of a pair of toggle-levers, one of whichincludes links 21 and 22 and the other of which includes links 23 and24. The links 22 and 24 are pivotally connected by means of a pivot-bolt25, which is engaged with the sill 20 and is braced at its upper end.above the links by a metallic strap 26, as shown. The links 21 and 23are pivotally connected by a bolt 27, which engages the plates 29 and 30above and below the links and'which are secured to the upper and lowerfaces, respectively, of the plungerrod, the several links being halvedat their ends in order that they may all lie in a common horizontalplane.

In order to operate the toggle-levers, a windlass-shaft 31 is rotatablymounted in the ,sill 20 and-within the inclosure of the levers, whichshaft has the usual sweep 32 fixedto its upper end, while a winding-drum33 is mounted loosely on the shaft and in the plane of thetoggle-levers, this drum having at- IOO tached to its periphery atdiametrically opposite points the ends of chain-sections 34 and 35, theopposite ends of which are connected with their respectivetoggle-levers, so that as the drum is rotated the chain-sections will bewound thereon and the toggle-levers will be operated to advance theplunger` for the compressing operation. When the plunger is released, itis returned by a helical spring 3G, which is attached at one end to theplungerrod and at its opposite end to the sill.

To alternately rotate and release the winding-drum, so that it may havean oscillatory movement, a latch 40 is pivoted upon the upper end of thedrum and is limited in its pivotal movement in one direction by means ofa pin LIl upon the upper end near the edge of the drum, the latch beingheld normally against the pin by means of a helical spring 4t2, attached'at one end to the drum and at the other to an arm 3, extending at rightangles to the latch and from a point at the opposite side of the pinfrom the fulcru 1n of the latch. The opposite end of the latch, whichprojects inwardly of the drum, has an engaging hook 4A, and this hookengages alternately with the ends of a double arm 45, which is fixedupon the shaft 31. In the path of movement of the opposite end of thelatch is a plate or lug 45', mounted upon the link 24, and when thelatch strikes this lug it is moved on its pivot to release the engagedend of the arm 45.

The operation of the plungeroperating mechanism is as follows: The partsbeing in the positions shown in Fig. l, if the outer end of the sweep ismoved to the left the engagement of arm 45 with the latch-hook willcause the drum to rotate with the sweep and wind the chains 3a and 36upon the drum, thus drawing the togglelevers inwardly and projectingtheir ends to move the plunger forwardly. The lug 45 is so positionedthat when the plunger is about to complete its forward movement thelatch will strike the lug, and further movement of the drum causes thelatch to swing upon its pivot and release the arm. The drum being thenfree of the shaft, pressure upon the plunger is released and its springreturns it, causing the sides of the toggle-levers to move outwardly andthe drum to return to its former position. The opposite end of thedouble arm then moves into engagement with the latch and the plu nger isagain moved forward, there being thus two operations of the plunger' foreach complete rotation of the windlass-shaft.

The sweep is adapted for the attachment of a draft-animal thereto, asshown.

With this construction it will be seen that a great pressure can beapplied to the compressing` operation and that the ends are properlytucked into the press-box; also, that the entire apparatus is simple andefficient.

In practice various modifications of the structure shown may be made,and any suitable materials and proportions may be used for the variousparts, without departing from the spirit of the invention.

What is claimed isl. A press comprising a press-box and a plungeroperable therein, a rotatable shaft provided with operating means, adrum upon the shaft, a toggle-lever connected with the plunger foroperating it, a chain connected with the toggle-lever and with the drumto be wound upon the latter to operate the togglelever, a latch upon thedrum for engagement with the shaft to rotate the drum therewith, andmeans carried by an element of the toggle-lever for engagement with thelatch to operate the latter to release the shaft.

2. A press comprising a press-box and a plunger operable therein, arotatable shaft provided with operating means, a drum on the shaft, atoggle-lever at each side of the drum and connected with the plunger,chains connected with the toggle-levers and with the drum to be wound onthe latter, an arm fixed to the shaft, a latch upon the drum forengagement by the arm to rotate the drum, and means in the path ofmovement of the latch for moving it pivotally to release the arm andpermit return movement of the plunger.

3. A press comprising a press-box and a plunger operable therein, arotatable shaft provided with operating means, a drum mounted loosely onthe shaft, a toggle-lever at each side of the drum and connected withthe plunger, chains connected with the toggle-lever and with theperiphery of the drum, an

larm fixed upon the shaft, a latch pivoted upon the drum for engagementwith the arm to lock the drum to rotate with the shaft, a stop in thepath of bodily movement of the latch to move it pivotally and releasethe arm, means for returning the plunger, an arm upon the latch and aspring connecting the latcharm and the drum and adapted to hold thelatch yieldably in position for engagement by the arm upon the shaft.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
